GitHub - maitrungduc1410/NativeScreen: Free, open-source screen recorder and demo video editor for macOS and Windows. Auto zooms, smooth cursor, captions, and a multi-track timeline.

See it move on the website.

Why Native Screen

• A real multi-track timeline. Zooms, blur and spotlight masks, captions and keyboard shortcuts each get their own tracks, as many as you need. Overlap two blurs, stack caption lines, drag items between tracks, snap everything to edges and the playhead.
• Automatic polish. Zooms follow your clicks and typing, the cursor glides instead of shaking, and motion blur makes fast moves look filmed.
• Everything stays on your machine. Recording, captions, transcript editing, sensitive data detection and export all run locally. No account, no upload, no watermark.
• Native, not a web wrapper. SwiftUI, AppKit and Metal on macOS, WinUI 3 and Direct3D 11 on Windows, with the system's own windows, menus and shortcuts. Hardware encoding, no FFmpeg, and no CPU use while the editor sits still.
• Let an AI agent do the editing. Claude, Codex, Cursor and other MCP clients can record, edit, restyle and export through the app. Every change lands in the editor you see and can be undone.
• Light and dark, and eight languages: English, Tiếng Việt, 简体中文, 日本語, Deutsch, Français, Español and Português (Brasil).

Features

Record

• Whole display, one window or a selected area, at native resolution and up to 60 fps.
• Camera, microphone and system audio as separate tracks. Pause and resume.
• Crash safe: the recording is written in small pieces, so a lost take can be recovered.

Edit

• Cut, trim, speed up and merge clips. Typing bursts are found for you and can be sped up in one click.
• Zoom track with automatic and manual zooms, or a loupe that magnifies one spot.
• Blur and spotlight masks on as many tracks as you need, plus automatic detection of emails, keys and faces.
• Keyboard shortcuts shown as 3D keycaps on their own tracks.
• Wallpapers, gradients, padding, shadows, device frames, crop, and aspect ratios for every platform with safe zones for Reels, TikTok and Shorts.
• Camera layouts, styles and background removal.
• Undo everything. Presets to reuse a look across projects.

Captions and transcript

• On-device captions with line or word animation and per-caption styles.
• Edit by transcript: remove filler words and tighten pauses in one pass, or cut a sentence by deleting its words.
• Export captions as .srt.

Export

• MP4, ProRes and GIF, 720p to 4K, hardware accelerated.
• Quick export to a file or straight to the clipboard, still frames as PNG or JPEG.

Install

macOS. Open the DMG and drag Native Screen to Applications. The app is signed and notarized by Apple. On first launch macOS asks for Screen Recording permission, and for camera and microphone when you turn them on. Updates arrive inside the app (Native Screen > Check for Updates...).

Windows. Signing certificates cost money every year, and Native Screen is free and open source, so the Windows build is not code signed yet. We will look for a way to improve this. For now Windows SmartScreen shows a blue "Windows protected your PC" screen the first time. Click More info, then Run anyway. You can check the download against the SHA-256 shown on the release page. Updates install themselves after that.

Let an AI agent drive it

Turn on Settings > AI Agents in Native Screen. The page shows the exact command for your machine, for example:

claude mcp add nativescreen -- "/Applications/Native Screen.app/Contents/MacOS/Native Screen" --mcp

Then ask things like "record my browser window for 20 seconds, zoom in on every click, add captions and export a 1080p MP4". The agent talks to the running app over a local socket that only your user account can open.

🎬 Demo placeholder (AI agent, ~15 s, sped up): a terminal with an agent on the left, Native Screen on the right. The agent's tool calls scroll by while zooms and captions appear on the timeline and an export finishes.

Build from source

macOS: Xcode 27 or later.

open macos/NativeScreen.xcodeproj

Run the NativeScreen scheme. Local builds have no updater, so they never replace themselves with a release.

Windows: .NET 10 SDK and the Windows App SDK workload, on Windows 10 or 11.

dotnet run --project windows/src/NativeScreen.App -c Debug -p:Platform=x64

pwsh windows/scripts/verify.ps1 builds everything and runs the tests.

Repository

Projects are folders (.nativescreen) with a documented JSON format (spec/02), so the same project opens on both platforms.
